check if value exist first

Description

Attempting to access the value of *o.Auth, when this field has no value, will give us the invalid memory address error
And users are allowed to not defined this value because it comes with a default value: https://www.terraform.io/cloud-docs/api-docs/admin/settings#request-body-3

Nice! Was it just something you noticed?

Not really. The error just pop up in my head by association.
I was adding an include field to listOptions in run_trigger.go and making changes around the valid() helper function.
The value passed is not part of a map then the option passed is invalid, right? This implementation works fine here because if the value is not defined at all, _, isValidRunTriggerType := validRunTriggerType[o.RunTriggerType] this line will just return false, not panic (o.RunTriggerType it's just an empty string).
Suddenly that reminded me that o.Auth field is not just a string but a pointer to a string, and there you go.
